2-position shrouded header with friction lock
The 3-644893-2 is the 2-circuit member of TE's CST-100 shrouded header line, designed for board-to-wire connections with a friction lock that holds the mating housing in place.
Position count and locking within CST-100
At 2 positions the 3-644893-2 is the smallest circuit-count option in the CST-100 series — the same 0.100" pitch, 4-wall shroud, and friction-lock design carry across all position counts, so the mating receptacle and terminal are shared within the family.
